Attiny Pocket Sequencer [Project]
posted June 20 2014 11:52.55 by spic0m

Adam Berger posted an instructable for making a small sequencer utilizing an attiny85:

"Music sequencers are awesome tools for producers, composers, and anyone looking for some musical inspiration. However, almost all sequencers available today are rather large devices with all sorts of cords. Wouldn't it be great if you could compose a sequence on the go and still have the record-able quality of a full sequencer?

Using an attiny85 I've developed this battery powered, pocket-sized sequencer which is fully programmable and usable in a studio setting, but in a smaller package. Here are some of the features:

-8 programmable steps

-8 LED display

-Potentiometer used for note frequency, tempo, and note length.

-Volume potentiometer.

-Onboard speaker.

-Mono audio-out 1/4 jack (selectable via a two-way switch)

-Two buttons, one for entering programming mode, one for selecting step or entering note length mode.

Besides making a pocket-sized sequencer, my goal of this project was to stretch the uses of the attiny chips to show how powerful they really are. This project is great for those interested in music and/or electronics, and by the end you will have one of the smallest, unique sequencers ever made!"
